NDIA California Residential Broadband Map


NDIA has launched a new version of our California residential broadband map. The map has several unique features, among them:

  • It brings data on broadband availability, service speed and adoption into a single interface.
  • It allows for comparing change over the years.
  • It compares advertised and actual speeds (based on Ookla data) at census block group level (or larger).
  • It measures ISP competition at different speed tiers (25/3, 100/20, fiber).
  • It includes information on geographies other than those provided by the census bureau, such as cities and tribal communities.
